The graph shows development of specific CO2 emissions, defined as emissions of CO2 per transport unit (tonne-km), by freight transport mode (road, rail, maritime, inland shipping) over the period 1995 to 2009.
Specific CO2 emissions data for all transport modes are modelled data derived from TREMOVE (http://www.tremove.org/model/index.htm) and TRENDS (http://www.forum.europa.eu.int/Public/irc/dsis/pip/library?l=/environment_trends).
Specific CO2 emissions are expressed in grams per tonne-kilometer.

Some 97.5% of water on the Earth is salt water, leaving only 2.5% as fresh water. Of this over two thirds is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater, with only a small fraction present in rivers, lakes or in the air. Water is a precious resource, use it responsibly and don’t waste it!
